f STENGIL.

This invention relates to an improvement in stencils wherein signs or the like may be readily and quickly painted upon appropriate surfaces by and with the use of the stencil.

The improved stencil consists in outlining the letters or sign upon a suitable fabric base inmaterial designed to be acted upon .by a solvent, then covering the surface of the letters and remaining portions of the fabric of the stencil with a substance which is not adectedby the solvent, then applying` the solvent so as to dissolve the material with which the letters or sign 'Was outlined; and then applying the desired paint over the stencil so that such paint Will penetrate through the outlined portions of the letters which have been cleared by the solvent.

The invention isillustrated in the accompanying drawings, in which:

Fig. 1 is a face view of a stencil or portion thereof with the letters outlined there- Fig. 2 is a similar view, with the protective covering applied.

Fig. 3 is a similar view of the completed stencil ready for use.

Tn carrying out the process, a stencil body 1 of appropriate size is provided. This body is of fabric, preferably of silk, which has been loosely. Woven to provide minute openings. The desired sign letters indicated at 2 are first outlined on one surface of the fabric, the material used being that which will respond to the use of a subsequent solvent, as for example, Where turpentine is used as a solvent, ordinary varnish may be used as the material for outlining the letters or characters. i

The Isurface of the stencil at least for some distance beyond the sign characters is then coated with a material which will notrespond to the solvent, say for example, glue. This may be, and preferably is, evenly applied by any suitable straight edge, `which after the glue is spread upon the Appueationnled september 14, 1925. serial No. 56,303.

solve the varnish from the fabric but will not affect the glue on the fabric.v The stencil is then laid upon the surface on which it is desired to apply the characters and the paint or other permanent material spread over the surface of the stencil at least to the extent of including the characters. This paint passing readily through the fabric in the space cleared by the solvent Will outline the letters uponthe surface on which the stencil is placed.

It is apparent that the stencil body of fabric may be readily cleansed from the paint and glue so that it may be used over and over for stencil purposes.

Tt is of course to be understood that the varnish may simply define the outline of the letters or characters of the sign, or may cover the full breadth marking of the character, this beinga detail depending upon the desired result in the` use of the paint.

V'Vhat weclaim is:

The process of producingI a stencil, consisting in outlining on a fabric body desired characters through the use of a material readily soluble in a particular solvent, the material filling the openings of the fabric, next coating the. face of the fabric and outlined characters with a material unresponsive to said solvent, the unresponsivev material filling the openings in the fabric, next reversing the fabric and applying thesolvent to the full surface thereof to thereby dissolve from the openings in the fabric the soluble material used in forming the characters, and then spreading a pigment or paint over that portion of the fabric from which the soluble material has been dii-solved.

Tn testimony whereof we aliix our signa tures.
